SPECIFICATION forming part of Letters Patent No. 790,785, dated May 23, 1905.

Application filed November 15, 1904. Serial No. 232,860.

To r1, whom it may concern:

Be it known that I, (JrIAUNcnY B. CowLns, a citizen of the United States, residing at Enid, in the county of Garfield andTerritory of Oklahoma, have invented certain new and useful Improvements in Draft-Equalizers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to draft-equalizers; and it consists of certain novel features of combination and construction of parts, the preferred form whereof will be hereinafter clearly set forth, and pointed out in the claim.

The prime object of my invention, among others, is to produce a draft-equalizer suitable for four horses possessing great simplicity and reliable efiiciency of operation.

A further object is to provide an equalizer of the character specified which will enable the draft-animals to be readily controlled and turned within a comparatively small space, the plow or other instrument being turned by a direct pull of the horses.

Another object is to provide means for placing the draft-animals mainly to one side of the line of draft, a valuable and important desideratum, inasmuch as the draft-animals may thus be disposed so that they will walk outside the uncut wheat or other grain, and thus avoid trampling the same.

Other objects and advantages will be hereinafter made clearly apparent, reference being had to the accompanying drawings, which are made a part of this application, and in which Figure 1 shows a top plan view of my invention complete as applied to use upon the end of a plow-beam or section of a reaper or hinder tongue. Fig. 2 shows a sectional view of Fig. 1 on line 2 2. Fig. 3 is a sectional view of Fig. 1 on line 3 3 thereof.

For convenience of description the various parts of my invention and cooperating accessories will be designated by numerals, the same numeral applying, to a similar part throughout the several views, and, referring to the numerals on the drawings, 1 and 2 indicate parallel bars secured to the end of the plow-beam or binder-tongue in any preferred way, as by the bolts 3 or the equivalent thereof. .The outer free ends of the bars 1 and 2 are preferably curved away from each other, so as not to interfere with the movement of the swingletrees incident to the use thereof. The plate 1 carries near its outer end the bar 1, held in place by the bolts 5 and 6, and interposed between the bar 1 and the outer end of the bar 4: is the laterally-extending arm 7, the outer end of which is connected to the chainsection 8, placed in communication with the stay-rod 9, the rear end of said rod being pivotally secured to the ear or bracket 10 or equivalent thereof, said bracket being carried by a contiguous part of the plow-beam or tongue, as the case may be. I also provide the auxiliary arm 11, which is disposed parallel with the arm 7 and is pivotally secured, as by the bolt 12, near the outer end of the bar or plate 2, before referred to, and I interpose between the arms 7 and 11 the maintree 13, secured in position by the bolt 14 passing through the outer ends of the arms 7 and 11 and through the washer or block 15. I pivotally secure to the inner end of the maintree 13 the doubletree 16, to which is attached in the usual manner the swingletrees 17 and 18, while to the outer end of said maintree I connect in the usual manner the outer doubletree 19, which carries the swingletrees 20 and 21, connected thereto in the usual way.

Inasmuch as the inner end of the maintrce 13 is left free to play back and forth between the parallel bars or plates 1 and 2, it follows that the pivot-point of said maintree is upon the bolt 14: and that the main force exerted in pulling the plow or machine, as the case may be, is disposed upon said bolt 14 and incidentally upon the stay-rod 9, it being understood that the arms 7 and 11 also serve their purpose of sustaining the stay-rod at substantially the angle set forth in the drawings.

It will thus be seen that I have provided a combination equalizer which may be used on plows or other machinery and which will exert a direct pull thereto and that is equally applicable for use upon plows and upon binders, reapers, and other heavy machinery where it is desirable to dispose the draft-ani-
